Device for carrying coiled material such as a coil of barbed wire

ABSTRACT

A device adapted to carry a coil of wire or the like includes a cylindrical ring having an outside diameter about the same as the inside diameter desired for the coiled material, at least one radial projection extending outwardly from one end of the ring a distance sufficient to support the coil thereon, and a handle connected to the ring and adapted to carry the device and the coiled material thereon. The device is particularly effective for carrying coils of barbed wire. Despite the fact that only a fraction of a coil of barbed wire is supported directly by the cylindrical ring and radial projection, the layers of the coil do not sag because of their mutual coherence and adequately support the coil. In producing the coiled material the device may be mounted on the winding mandrel of a winding machine.

7 Claims, 7 Drawing Figures BACKGROUND OF THE INVENTION 1. Field of theInvention The present invention relates to apparatus for carry ing acoil of wire, cable or strapping material, such as barbed wire, to acoil of such material wound around such apparatus and to a method forcoiling up material on such apparatus.

2. Description of the Prior Art Wire coils, such as coils of barbedwire, are normally wound on a spool (which itself may be made of metalwire) provided with a handle to facilitate the manipulation of the wirecoils. A handle is particularly necessary in the case of coils of barbedwire so as to prevent the barbs from causing injuries. However, thedesign of conventional spools is such that a substantial amount ofundesirable extra weight is added to the coils of material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, thecarrying device embodying the present invention includes a cylindricalring 11, around which a coil of barbed wire 12 may be wound,

and a handle 13. The ring 11 is provided at its bottom side with aradially projecting ring flange l4 and at its upper side with axial lipsor projections 15 to which handle 13 is flxed. The handle 13 consists ofa U- shaped piece of wire having two legs 16 and a base 17. The freeends of the legs 16 are bent to the outside and engage with pre-tensionfrom the inside through openings in the projections 15. The wire of thehandle 13 may be coated with aprotective layer of synthetic material.The length of the base 17 between the legs 16 approximately correspondsto the inside diameter of the central opening 18 of the coil of barbedwire 12 as shown in FIG. 2.

As can be seen in FIG. 3, the axial length or height of the cylindricalring 11 corresponds to the height of a layer of a few windings of thewire coil 12. The length or width of the radial projection of the ringflange I4 is normally designed in such a way that the flange 14 engagesbetween adjacent windings of the wire at the open inside surface of coil12. Instead ofa circular ring flange, or as an extension thereof, radialprojections may be fixed at spaced points on the outer side of the ring.

FIGS. 4a and 6 show a modification of the device of the presentinvention in which the outer surface of the ring is provided with spacedprojections 19, 20 and 21 in addition to the ring flange 14. The ringflange 14 is also provided with a radially projecting lip 21 under theprojection 20. The radial projections 19 and 21 provide a reinforcementof the ring 11 and in addition provide particular points of contact onwhich the windings of barbed wire exert a lateral pressure and throughwhich extra tension originates as an aid to prevent the windings fromslipping off.

As can be seen particularly in FIGS. 2 and 3, the ring 11 is located inthe central bore 18 in such a way that the top edge of the ring and thetop surface of the coil are essentially at the same level with the lips15 which are provided for attaching the handle projecting thereabove.The hinge joints are thus located free from the coil of barbed wire, sothat the handle 13 can be freely swung down on the upper plane of thecoil, as can be seen in particular in FIG. 3.

The ring 11, the ring flange l4 and the projections such as 15 normallywill be made in one piece and, preferably, of a synthetic material suchas a plastic (e.g. polyethylene).

When piling up a number of coils, the collapsible handle may also beused to improve the stability of the pile, namely by positioning thehandle upright and having it engaged in the central bore of the coilimmediately thereabove. The coils are preferably piled up in such a waythat the plane of the handle of an underlying coil is in each caseperpendicular to the plane of the handle of the coil placed thereupon.

A typical coil of barbed wire would have, say, an outside diameter ofapproximately 30 to 40 cm, an inside diameter of approximately 10 to 12cm and a height of approximately 20 to 30 cm. In such a case, the axiallength of the ring 11 or the carrying device would preferably measureabout 2cm, the radial width of the ring flange would be approximately0.3cm and the thickness of the ring material would be approximately0.30m. In practice, a light weight material is normally entirelysuitable for the bearing ring.

When using a ring of the type shown in FIGS. 4a and 6, no upwardprojecting lips (e.g. lips 15) need be employed for engaging the legs 16of the handle 13, since two especially designed ribs 20 fixed atopposite sides of the outside of the ring 11 are used for this purpose.Approximately in the center, each of these ribs 20 is provided with aperforation or hole which continues through the ring 11; the rib 20 isalso provided at this point with a depression or groove 22 whichcontinues in an upward direction in the plane of the rib 20 which isobliquely cut off and turned back to the inside. The bent end 23 of theleg 16 is located almost completely in the depression or groove 22 ofthe rib 20 so that the turning of the handle 13 is not hampered by anywindings running over these ribs.

Thus, it will be seen that the carrying device of the present inventioncomprises a substantially cylindrical ring and a handle attached to thisring, wherein the height of the ring corresponds to the height of only afew piled up windings of the coiled material and wherein the ring isprovided with radially outward projecting elements. The radiallyprojecting elements of the ring may simply consist of a ring flangeformed by raising the bottom edge of the ring.

When the carrying device supports a coil of coilable material, the ringis positioned inside the coil with a few (or a fraction) of the windingsof the coiled material resting directly against the ring. The radiallyprojecting elements of the ring are engaged between adjacent windings ofthe coil and these provide the supporting connection for the ring insidethe coil.

The handle projects from one side of the coil. The ring is preferablylocated in the center bore of the coil in such a way that the top edgeof the ring lies approximately in the same plane as the upper side ofthe coil and so that the turnability of the handle is not prevented. Atthe top edge of the ring, upward projecting lips or similar projectionsmay be provided, which mainly protrude in an axial direction and towhich the handle is attached. When carrying a coil by means of thehandle of the carrying device of the present invention, the layers ofthe coil do not sag, apparently because of their mutual coherencedespite the weight of wire coil beneath the ring.

The length or width of the radially projecting elements, which mayconsist of simply a ring flange, is preferably at least equal to thethickness of one layer of coiled material, thus allowing the projectingelements to engage far enough between the windings of the material inorder to provide a firm fixation of the ring in the coil. in practice,the inside diameter of the ring will be approximately equal to thediameter of the mandrel ofthe winding machine, on which the coils arewound during their formation, so that the ring can be slipped beforehandon the mandrel of the winding machine. When winding a coil, at least afew windings of the first layer of the coil are wound directly on thering and thereafter the next part of the winding process normallyproceeds directly on the mandrel. After finishing the coil, the handlemay be fixed to the ring and employed to remove the coil from themandrel.

Inasmuch as the present invention is subject to many variations,modifications and changes in detail, it is intended that all mattercontained in the foregoing description or shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitingsense.
